I want implement a many to many relationship such that one person can join multiple social clubs and one social club can have multiple members. This is how far I've got but this doesn't display the movie details and serialization gives me an error -
Original exception text was: 'ManyRelatedManager' object has no attribute 'club_name'.

models.py

class Club(models.Model):
  club_name = models.CharField(default='',blank=False,max_length=100)

class Person(models.Model):
  person_name = models.CharField(default='',blank=False,max_length=200)
  clubs = models.ManyToManyField(Club)

serializers.py

class ClubSerializer(serializers.ModelSerializer):
  class Meta:
    model = Club
    fields = ('url','id','club_name','person')

class PersonSerializer(serializers.ModelSerializer):
  clubs = ClubSerializer()
  class Meta:
    model = Person
    fields = ('url','id','person_name','clubs')

views.py

class ClubDetail(generics.ListCreateAPIView):
serializer_class = ClubSerializer

  def get_queryset(self):
    club = Clubs.objects.get(pk=self.kwargs.get('pk',None))
    persons = Person.objects.filter(club=club)
    return persons

class ClubList(generics.ListCreateAPIView):
  queryset = Club.objects.all()
  serializer_class = ClubSerializer


class PersonDetail(generics.RetrieveUpdateDestroyAPIView):
  serializer_class = PersonSerializer


def get_object(self):
  person_id = self.kwargs.get('pk',None)
  return Person.objects.get(pk=person_id)

urls.py

urlpatterns = format_suffix_patterns([
url(r'^$', views.api_root),
url(r'^clubs/$',
views.ClubList.as_view(),
name='club-list'),
url(r'^clubs/(?P<pk>[0-9]+)/persons/$',
views.ClubDetail.as_view(),
name='club-detail'),
url(r'^person/(?P<pk>[0-9]+)/$',
views.PersonDetail.as_view(),
name='person-detail'),
])

on my local server, I get the clubs list which navigates me to clubdetail view,but it doesn't show the movie names or, but I can't see the person list. How do I do this correctly?

ここのコードには多くの問題があります。すなわち：

  • ClubSerializer.Meta.fields - person は person_set にする必要があります
  • PersonSerializer - クラブはclubs = ClubSerializer(many=True)
  • ClubDetail.serializer_class - ClubSerializer は PersonSerializer である必要があります
  • ClubDetail - クエリセットはpersons = Person.objects.filter(clubs=club)

上記を修正するClubDetailと、クラブ メンバーのリストに移動して表示できるようになります。
